What are the synthesis methods of 3-iodo-9h-carbazole?

3-Iodo-9H-carbazole, or 3-iodine-9H-carbazole, is synthesized by various methods, which are described in detail below.
First, carbazole is used as the starting material and can be obtained by halogenation reaction. Usually in a suitable reaction vessel, carbazole is dissolved in a suitable organic solvent, such as dichloromethane, N, N-dimethylformamide, etc. Then a halogenating agent is added, such as iodine elemental ($I_ {2} $) and a suitable oxidizing agent, commonly such as hydrogen peroxide ($H_ {2} O_ {2} $) or potassium persulfate ($K_ {2} S_ {2} O_ {8} $). At appropriate temperature and reaction time, the oxidizing agent prompts the electrophilic substitution reaction of iodine with carbazole, mainly introducing iodine atoms at the 3rd position of carbazole to obtain 3-iodine-9H-carbazole. This method is relatively direct and the conditions are relatively mild. However, it is necessary to pay attention to the reaction selectivity and avoid the formation of polyhalogenated products.
Second, it is prepared by a coupling reaction catalyzed by transition metals. First, carbazole is properly functionalized, for example, carbazole is made into borate esters or halocarbazole derivatives. If carbazole borate is prepared, carbazole can be formed by reacting with the corresponding borate ester reagent under the action of a base and a transition metal catalyst (such as palladium catalyst, such as tetra (triphenylphosphine) palladium ($Pd (PPh_ {3}) _ {4} $)). Subsequently, the carbazole borate and iodine reagents (such as iodoaromatics or iodoalkanes) under basic conditions and palladium catalyst undergo Suzuki coupling reaction, which can introduce iodine atoms at the 3 position of carbazole to generate the target product 3-iodine-9H-carbazole. This method has the advantage of high selectivity and can effectively construct carbon-iodine bonds, but the catalyst cost is high and the reaction conditions are relatively strict.
Third, the guide group strategy can also be used. Introduce a specific guide group on the carbazole molecule, which can coordinate with a metal catalyst to guide the halogenated reagent to selectively react at the 3 position of carbazole. For example, introduce a guide group such as pyridyl, and react with an iodine source under the catalysis of transition metals (such as copper, palladium, etc.) to complete the synthesis of 3-iodine-9H-carbazole. After the reaction, the guide group can be removed by suitable methods. This strategy precisely controls the selectivity of the reaction check point and greatly reduces side reactions. However, the introduction and removal of guide groups increase the complexity of the reaction process.

What is the price range of 3-iodo-9h-carbazole in the market?

3-Iodine-9H-carbazole, the price in the market, it is difficult to determine. The price of the cover varies due to many reasons, such as the quality of the quality, the situation of demand and supply, the simplicity of the manufacturing process, and the wide and narrow market.
If the quality is high and pure, the price will be higher than that of ordinary products. There are many people who ask for it, and there are few people who supply it, the price will rise; on the contrary, if the supply exceeds the demand, the price will drop. Furthermore, if the preparation requires complicated methods and expensive materials, the cost will increase and the price will also be high. Different cities, such as remote and prosperous places, have different prices.
In the market of various trading fields and chemical materials, there may be a price. However, with the changes in the present, the range of its price cannot be determined. Ask a merchant specializing in chemical raw materials, or you can get a recent price. If you want to know the price widely, you can visit the platform, forum of the chemical industry, or have a colleague tell you. Or check the information site of the chemical price to find out the approximate price. However, it is not accurate, it is for reference only.
